Title: Improvements in or relating to brake mechanism for use with trailers
IPC: B60T7/20
Filed: 1931-09-14
Abstract: 394,323. Brakes for trailers. CLARKE, C. V., 171, Tavistock Street, Bedford. Sept. 14, 1931, No. 25740. [Class 103 (i).] A trailer brake is released bv movement of the tow-bar due to forward movement of the tractor and comprises means, e.g. fluid-pressure for holding the brake in released position, which fluid-pressure is released by the driver to affect application of the brake. The drawbar 1 slides in a housing 6 and has a piston 2 sliding in a cylinder 3 on the trailer. A collar 4 fixed to the draw-bar bears on a shoulder on a sleeve 5 connected by a hub 14 and a liner 15 to the brakes. A spring 7 is compressed between the sleeve 5 and the bearing 6 when the tractor moves forward and oil is drawn through valves 9, 10 from a reservoir 8 into the cylinder 3 and holds the trailer brakes released. The brake application is initiated by a Bowden control 13 from the tractor, wbich is adapted to open the valves 9, 10 and release the oil into the reservoir and allow the spring 7 to apply the brakes until a further acceleration of the tractor releases the brakes. When the tractor is stopped suddenly, overrunning of the trailer produces a further braking through a spring 19 between the collar 4 and a sleeve 18 fixed to the sleeve 5. The sleeve 18 finally comes against a buffer stop 24 to limit the movement of the draw bar. The extent to which the spring 19 is compressed may be regulated by an adjustment device. Seating in the valve 10 is the valve 9 which is small and can be easily opened against the fluid-pressure which is partially relieved and allows the valve 10 to be easily opened by the collar 12 on the rod of the valve 9. To the liner 15 is secured an extension 20 attached to the cylinder portion 21 of a shock absorber which allows the trailer to be started without shock. The parts of the Bowden wire 13 are detachably connected by a hook 31 and pin 32 to the valve lever 12<1> and a wing nut 34 to a fixed part. The spring 7 may be replaced by a spring 30 where a minimum length of draw-bar is desired. In a modification the spring 7 is replaced by three springs, a cable connects the sleeve 5 to the brakes and the shock absorber is arranged over the springs. Attached to this cable 1 is a cable connected to a collar adapted to be turned by a key to release the brakes by hand when the trailer is detached. The shock-absorber is mounted between the collar 5 and the bearing 6. The valves 9, 10 may be substituted by valves consisting of inner and outer forked sleeves. If the trailer breaks away the brakes will be applied by the tension on the cable 13 before it breaks.

Title: Improvements in or relating to connections for connecting and disconnecting a parachute to and from its load
Inventor: ANDERSON GEORGE
IPC: B64D17/38
Filed: 1953-09-17
Abstract: 782,667. Hooks; time-delayed fastenings. NATIONAL RESEARCH DEVELOPMENT CORPORATION. Dec. 7, 1954 [Sept. 17, 1953], No. 25765/53. Classes 44 and 89(2) [Also in Group XXI] A hook-device for connecting and disconnecting a load to and from a parachute, comprises a body 1 with end-cap 2 and sidearms 2b, between which is pivoted hook 4 to engage a load-link 7 and encased by a cover 21. The load tends to turn the hook to release link 7 but is prevented by the hook abutting a trip-lever 9 which is urged by a spring 14 to release the hook, and which engages, by a detent 15, a stop 16. Stop 16 is attached to a time-delay mechanism, e.g. a dashpot, or a gear-driven escapement 17, which includes a pallet and is actuated by a spring 19 through a stationary screw 34 engaging the threaded bore of the first gear of the escapement. The hook-device is loaded by removing a cover 21 and hook 4 with pivot 5, rotating lever 9 against spring 14, pulling down stop 16, engaging detent 15 in recess 18 of the stop, replacing the hook with link 7 in position and finally replacing cover 21. In use, the sudden force as the parachute opens causes lever 9 to turn slightly and move detent 15 out of recess 18, whereupon spring 19 moves mechanism 17 through clearance 34a between a crew 34 and cap 2. Thus, detent 15 can no longer engage recess 18 and spring 19 causes operation of mechanism 17 which ultimately abuts cap 2 with stop 16 clear of lever 9. In this condition, the hook will remain closed so long as the drag exceeds the force of spring 14, but lever 9 will trip when spring 14 predominates, whereupon any drag will turn hook 4 anti-clockwise and release link 7.

Abstract: 616,123. Rim brakes. DURAND, M. P. Aug. 28, 1946, No. 25799. Convention date, Nov. 8, 1944. [Classes 136 (i) and 136 (ii)] In a rim brake for bicycles and the like, the brake shoes are given successive displacements along parallel planes by the action of a parallel motion pivotally secured to two pivots 3 and 4 rigid with a stationary part 2 secured to the fork 1. The pivots 3 support straps 5 which pass to either side of sleeves 6 and are pivotally secured thereto by removable studs 7. Studs 8 pivotally connect the sleeves to the arms 9 of the control levers 10 which are pivoted at 4. Each lever 10 is pulled down by a spring 11. The sleeve encloses the tailpiece 13 of the shoe carrier which is secured by pin 15 with winged nuts 16. Rods 18 connect the control levers 10 to a cross-bar to which the operating cable 20 is attached. An inflated tyre can be removed readily by unhooking a spring 11, removing the corresponding stud 7 and rocking the sleeve 6 about the stud 8 as shown in Fig. 3. In a modification the central pull cable is replaced by a side pull cable.

Filed: 1945-10-06
Abstract: 600,968. Burglar alarms. JARDINE, G. R. F. Oct. 6, 1945, No. 26108. [Class 118 (i)] In an electric burglar or like alarm device in which a spring-controlled slidable bolt normally held under compression is arranged to be released and to project beyond an opening in a face plate to close electric contacts when the door, window &c. to which the device is attached is opened the bolt is laterally displaceable so that it can be retained with its end partly out of register with the opening in the face plate and means operating automatically for positively holding the bolt in its projected position. The arrangement comprising the bolt 4 in a housing 5 fitted with an end face 6 is sunk into a recess 7 in a door frame 8 such that the door edge 9, when closed, presses against the end of the bolt 4 thus holding it against the bias of a spring 11 in the position shown by full lines in Fig. 1. In this position the electric circuit through a contact 17, attached to the bolt shank 12, and a contact 18, fixed to, but insulated from, the housing 5, is broken. When the door is opened the bolt 4 which has previously been moved to register with the hole in the face plate springs into its fully projected position, shown in broken lines in Fig. 1, thus closing the contacts 17, 18 and energizing a suitable audible or visible alarm device connected to leads 19, 20. In the projected position a groove 13 in the bolt registers with the edge of the hole 10 in the face plate 6 under the action of gravity or of a spring-controlled pin 14 carried in a bracket 15. When the bolt is pushed back through the face plate the pin 14 presses it on to a ledge 21, Fig. 2, in the rear of the face plate. The necessary lateral movement of the bolt is provided by loosely mounting its shank 12 in a guide 16 on the housing 5. To set the device a suitable tool, inserted through the face plate and into a recess 22 in the end of the bolt, is manipulated to bring the end of the bolt 4 into register with the hole 10 in the face plate.
